Whoops, that’s right! Going to correct it now, thank you!

I believe
// println( “Raw Input:” + input);
in serialEvent should be:
// println( “Raw Input:” + val);
Unless input is some Prcoessing defined variable? (Only been using Processing < 1hr )

You may want to consider looking at the networking client/server examples for communication between machines as well. Otherwise, it’s hard to know why it isn’t working, perhaps use a console / terminal to make sure your serial ports and working and data is flowing before wondering if it’s an issue with your Processing code.

I tried to get two computers to talk to each other through the serial port using Processing. However, It hasn’t worked. I tried this book and you had this example. I couldn’t find where the +input was coming from for the debugging statement inside the serialEvent(). I don’t think that the serialEvent() function is getting called. If you have any tips on this, that would be great.
